Background. Laparoscopy is ever more common in both elective and emergency surgery. In fact, in abdominal emergencies it enables the resolution of preoperative diagnostic doubts as well as treatment of the underlying disease. We present a retrospective study of the results of a 5-year experience at a single center. Patients and methods. Between September 2006 and August 2011, 961 patients were treated via laparoscopy, including 486 emergency cases (15 gastroduodenal perforation; 165 acute cholecystitis; 255 acute appendicitis; 15 pelvic inflammatory disease and non-specific abdominal pain [NSAP]; 36 small bowel obstruction). All procedures were conducted by a team trained in laparoscopic surgery. Results. The conversion rate was 22/486 patients (4.53%). A definitive laparoscopic diagnosis was possible in over 96% of cases, and definitive treatment via laparoscopy was possible in most of these. Conclusions Our own experience confirms the literature evidence that laparoscopy is a valid option in the surgical treatment of abdominal emergencies. In any case, it must be performed by a dedicated and highly experienced team. Correct patient selection is also important, to enable the most suitable approach for each given situation.

The present study was aimed at assessing the experience of a single referral center with recurrent varicose veins of the legs (RVL) over the period 1993-2008. Among a total of 846 procedures for Leg Varices (LV), 74 procedures were for RVL (8.7%). The causes of recurrence were classified as classic: insufficient crossectomy (13); incompetent perforating veins (13); reticular phlebectasia (22); small saphenous vein insufficiency (9); accessory saphenous veins (4); and particular: post-hemodynamic treatment (5); incomplete stripping (1); Sapheno-Femoral Junction (SFJ) vascularization (5); post-thermal ablation (2). For the “classic” RVL the treatment consisted essentially of completing the previous treatment, both if the problem was linked to an insufficient earlier treatment and if it was due to a later onset. The most common cause in our series was reticular phlebectasia; when the simple sclerosing injections are not sufficient, this was treated by phlebectomy according to Mueller. The “particular” cases classified as 1, 2 and 4 were also treated by completing the traditional stripping procedure (+ crossectomy if this had not been done previously), considered to be the gold standard. In the presence of a SFJ neo-vascularization, with or without cavernoma, approximately 5 cm of femoral vein were explored, the afferent vessels ligated and, if cavernoma was present, it was removed. Although inguinal neo-angiogenesis is a possible mechanism, some doubt can be raised as to its importance as a primary factor in causing recurrent varicose veins, rather than their being due to a preexisting vein left in situ because it was ignored, regarded as insignificant, or poorly evident. In conclusion, we stress that LV is a progressive disease, so the treatment is unlikely to be confined to a single procedure. It is important to plan adequate monitoring during follow-up, and to be ready to reoperate when new problems present that, if left, could lead the patient to doubt the validity and efficacy of the original treatment.

The Whipple’ Disease (W.D.) is a very rare disease with an incidence of 1 per 1.000.000 inhabitants; it is a systemic infection that may mimic a wide spectrum of clinical disorders, which may have a fatal outcome and affects mainly male 40-50 years old. The infective agent is an actinomycete, Tropheryma Whipplei (T.W.) that was isolated 100 years after first description by Wipple, and identified in macrophages of mucosa of the small intestine by biopsy which is characterized by periodic acid-Schiff-positive, products of the inner membrane of his polysaccharide bacterial cell wall. The multisystemic clinical manifestations evolve rapidly towards an organic decay characterized by weight loss, malabsorption, diarrhea, polyathralgia, opthalmoplegia, neuro-psychiatric disorders and sometimes associated to endocarditis. Early antibiotic treatment with trimethoprim and sulfometathaxazole reduces the fatal evolution of the disease. The authors present a rare experience about a female subject in which the clinical gastrointestinal signs were preceded by neuro-psychiatric disorders, and evolved into obstruction and intestinal perforation which required an emergency surgery with temporary ileostomy, recanalized only after adequate medical treatment with a full dose of antibiotic and resolution of clinical disease for the high risks of fistulae for the edema and lymphadenopathy of mucosa. The diagnosis was histologically examined by intestinal biopsy performed during surgery, which showed PAS-positive histiocytes, while PRC polymerase RNA was negative, which confirms the high sensibility of PAS positive and low specificity of RNA polymerase for T.W.

This document does NOT address the issue of particle backscattering quality control (either real-time or delayed mode). As a preliminary step towards that goal, this document seeks to ensure that all countries deploying floats equipped with backscattering sensors document the data and metadata related to these floats properly. We produced this document in response to action item 9 from the first Bio-Argo Data Management meeting in Hyderabad (November 12-13, 2012). If the recommendations contained herein are followed, we will end up with a more uniform set of particle backscattering data within the Bio-Argo data system, allowing users to begin analyzing not only their own particle backscattering data, but also those of others, in the true spirit of Argo data sharing.

O objectivo do presente ensaio é o de levar a cabo uma análise da questão da contemporaneidade na obra do autor angolano Pepetela (Artur Carlos Maurício Pestana dos Santos), a partir da base teórica de “Contemporâneo como intempestivo” elaborada pelo filósofo Giorgio Agamben. Num contexto complexo como o de Angola em formação, numa realidade mergulhada nos problemas duma nação multi étnica e com um passado colonial marcado, a luta pela conquista duma identidade comum e da liberdade individual constituem umas das preocupações principais, unidas às complexas relações com o que permanece da cultura do colonizador.

Notre étude porte le western crépusculaire et cherche plus précisément à extraire le « crépusculaire » du genre. L'épithète « crépusculaire », héritée du vocabulaire critique des années 1960 et 1970, définit généralement un nombre relativement restreint d'œuvres dont le récit met en scène des cowboys vieillissants dans un style qui privilégie un réalisme esthétique et psychologique, fréquemment associé à un révisionnisme historique, voire au « western pro-indien », mais qui se démarque par sa propension à filmer des protagonistes fatigués et dépassés par la marche de l'Histoire. Par un détour sur les formes littéraires ayant comme contexte diégétique l’Ouest américain (dime-novel et romans de la frontière), nous effectuons des allers et retours entre les formes épique et romanesque, entre l’Histoire et son mythe, entre le littéraire et le filmique pour mieux saisir la relation dyadique qu’entretient le western avec l’écriture, d’une part monumentale et d’autre part critique, de l’Histoire. Moins intéressée à l’esthétique des images qu’aux aspects narratologiques du film pris comme texte, notre approche tire profit des analyses littéraires pour remettre en cause les classifications étanches qui ont marqué l’évolution du western cinématographique. Nous étudions, à partir des intuitions d’André Bazin au sujet du sur-western, les modulations narratives du western ainsi que l’émergence d’une conscience critique à partir de ses héros mythologiques (notamment le cow-boy). Notre approche est à la fois épistémologique et transhistorique en ce qu’elle cherche à dégager du western crépusculaire un genre au-delà des genres, fondé sur une incitation à la narrativisation crépusculaire de la part du spectateur. Cette dernière, concentrée par une approche deleuzienne de l’image-cristal, renvoie non plus seulement à une conception existentialiste du personnage dans l’Histoire, mais aussi à une mise en relief pointue du hors-cadre du cinéma, moment de clairvoyance à la fois pragmatique et historicisant que nous définissons comme une image-fin, une image chronogénétique relevant de la contemporanéité de ses figures et de leurs auteurs.

El objetivo principal de este proyecto es confeccionar material didáctico adicional audiovisual (vídeos) en inglés y en otros idiomas extranjeros para proporcionarlo a los estudiantes del Grado en Farmacia con la finalidad de mejorar su capacitación. Los objetivos alcanzados fueron: 1) Se confeccionaron el material didáctico y todos los documentos necesarios para el desarrollo del proyecto. 2) La mayoría del alumnado que aprovechó el material puso de manifiesto su satisfacción y la utilidad con respecto al proyecto y al material audiovisual. La franja de alumnado que no vio el material no lo hizo en más de la mitad de los casos por falta de tiempo. Según los resultados obtenidos, el grado de satisfacción es mayor entre el alumnado que vio más vídeos. 3) El proyecto tuvo un impacto positivo en el rendimiento de los alumnos. Este resultado no se observa si se comparan las calificaciones medias del grupo experimental y del grupo control, porque las calificaciones de la docencia práctica tienen de por sí una media elevada y eso no permite la apreciación del impacto positivo de esa variable. Lo que sí modificó la aplicación de este proyecto en la docencia práctica es la calidad del grupo experimental, ya que las calificaciones se concentran más alrededor del valor medio.

El desarrollo de los diálogos de paz adelantados desde el año 2012, entre el Gobierno de Colombia y las FARCEP, ha contado con varios inconvenientes a la hora de crear vínculos entre la propuesta de paz negociada y los ciudadanos. Esto en parte a que se han caracterizado por realizarse de forma reservada, informando solo de forma oficial los avances, asociado a esto han enfrentado episodios caracterizados por la desinformación y una intensa lucha por el discurso. A un nivel más profundo pero igualmente ligado al momento que vive el país, se encuentran las dificultades consecuencia de la prolongación del conflicto, que dificulta aún más establecer conexiones con los ciudadanos. A partir de las problemáticas mencionadas puede inferirse la necesidad de construir vínculos con los ciudadanos, tanto con la paz como con el conflicto. En respuesta a esta necesidad el gobierno colombiano a través del Grupo de Pedagogía para la Paz de la Presidencia de la Eepública, dio inicio en enero de 2016 al plan pedagógico y de participación ciudadana ‘La Conversación Más Grande del Mundo’. Una iniciativa promovida, para abrir la conversación a los ciudadanos en torno a la construcción de paz y la transición al postconflicto. El presente trabajo intenta determinar si el contenido compartido a través de página de Facebook ‘La Conversación más Grande del mundo’ está enfocado a la transformación del conflicto, identificando la presencia de sus principales características a través de un análisis de contenido de los textos usados durante los primeros cinco meses de su funcionamiento.
